Jody Lea, 23, of Maes yr Orsedd in Llandudno, received a 12-month community order of supervision and an order was made that she should not approach Mr Greenhalgh or Miss Murdock for the next 12 months. She also admitted affray.

Mold Crown Court heard how at the time, Williams and Smith had been staying at Lea’s home and she had taken them to the victim’s home in the belief that they could buy drugs.

Mr Recorder Fox said it was a particularly nasty incident – a premeditated visit to the couple’s house at night.

The two male defendants were large men and Williams was armed with a knife.

“You took part in a sustained attack, which was in the nature of torture,” the judge told them.

Prosecuting barrister Oliver King told how Mr Greenhalgh was woken by tapping noises at the lounge window and on two occasions went to the window.

Williams, whom he did not know, was there and mimicked smoking drugs.

He was told in no certain terms to go away but later Mr Greenhalgh answered a knock on the door, believing it was a member of his family.

The two male defendants burst in and Williams produced a knife with an 8inch blade and punched him several times to the left eye and cheek.

Williams demanded drugs, but Greenhalgh said he did not have any. However, the knife was used to cut his face and back and it was used repeatedly to threaten him.

“The victim describes himself as lying on the floor, on his side, wriggling in agony,” said Mr King.

Williams struck Miss Murdock on the face with the knife butt before leaving.

Jonathan Duffy, for Williams, said it was fortunate that Mr Greenhalgh made a full recovery. Williams was currently serving an indeterminate sentence following an attack on his partner.

Tony Rose, for Lea, said that his client had remained by the door throughout, she did not have a knife, but accepted her presence would have added to the victim’s fears.
